AVR254 CONNECTIONS There are different types of audio and video connections used to Bare wire cables are installed as follows (see Figure 2): connect the receiver to the speakers and video display, and to connect 1. Unscrew the terminal cap until the pass-through hole in the collar is the source devices to the receiver.
Page 16: Audio Connections
AVR254 CONNECTIONS Audio Connections If your video display or source device is not HDMI-capable, use one of the analog video connections (composite, S- or component video) and, There are two formats for audio connections: digital and analog. Digital if available on your source device, either a coaxial or optical digital audio audio signals are required for listening to sources encoded with digital connection.
Page 17: Video Connections
AVR254 CONNECTIONS required for DVD-Audio players compliant with HDMI version 1.1 or Composite better, or HD-DVD and Blu-ray Disc players that decode the digital audio video cable internally and output linear PCM signals in digital format. Consult the Figure 10 – Composite Video owner’s guide for your disc player for more information.
